Patented Feb. 2, 1943 warren SUPPORTING FRAME FOR RUCKSACKS AND THE LIKE Ernst Harald Wallin, Arvika, Sweden Application October 18, 1939, Serial No. 390,007 In Sweden March 23, 1938 1 Claim.

Supporting frames comprising a hip harness as well as two rails, tubes or the like connected at the lower ends with the said harness and at the upper ends with one another directly or indirectly by means of a cross piece, are old. However, the said known supporting frames have a number of drawbacks, and therefore they have not come into use to the desired extent. One of the most prominent drawbacks is that in view of the rigid construction of the supporting frames it is diflicult to transport a considerable number of rucksacks on motor cars or the like because the frames of those rucksacks which are placed lowermost are deformed by the pressure of the overlying ones. Moreover, they take up much space when loaded. For this mere reason the old supporting frames are not advantageous for military purposes. To serve these purposes they should also be adapted to suit persons of various size, and they should give the person carrying the rucksack a greater mobility than those hitherto used.

The present invention eliminates the drawbacks connected with the known supporting frames, and the frame according to the invention is characterized substantially by the fact that all or only some (the hip harness, the rails, the cross piece) of the elements of the frame are detachably and flexibly connected with one another.

An embodiment of the invention is illustrated on the accompanying drawings, in which Fig. 1 is a front View of the supporting frame mounted on a tent portion,

Fig. 2 a section on line II-II of Fig. 1, and

Fig. 3 a side View of the frame with packing placed thereon.

Fig. 4 is a detail, and

Fig. 5 a section on line V-V of Fig. 4.

Fig. 6 is a sleeping-bag adapted to be placed on the frame.

In the drawings the reference numeral l indicates the hip harness consisting of two parts a and b. The said parts are adapted to being lapfixed in difierent positions relatively to one another by means of a wing nut 2. The hip harness may be adjusted to suit persons with various waist width. One end of a rail 3 or 4 respectively is connected with the parts a and b respectively. The said rails may also be adapted to be elongated and shortened for example in the same way as the hip harness. At the top the rails 3 and 4 are connected with one another by means of a cross piece 5 to which the straps l4 and I5 are secured, which latter may be provided with tubular paddings 14*, I5, as shown in Fig. l. The elements serving to connect the hip harness, the rails 3 and 4 and the cross piece 5 with one another should all or most of them be so shaped as to obtain a certain flexibility between the parts. In the illustrated embodiment the rail 3 is detachably connected with the part a of the hip harness, for example by means of a wing nut 6, while a rivet 7 constitutes the connecting means between the said rail and the cross piece 5.

In order that the supporting frame shall be well adjusted to the size of different persons the distance between the connecting points of the rails 3, 4 with the cross piece should be variable. This is also possible in the present construction, the cross piece having been provided with a 1ongitudinal recess 8, in one edge of which there is a number of smaller recesses 9. A pin [0 connected with the rail 4 is adapted to be inserted in any one of the recesses 9. Thus, the rail 4, which is pivoted to the hip harness I by a rivet ll, may be adjusted to various distances from the rail 3 by insertion of the pin It in different recesses 9. In order to retain the pin [0 in the desired recess there is provided a member l2, suitably consisting of leather, which, when inserted in the recess 8, fills up the greatest part of the said recess and prevents a removal of the pin from the respective recess 9. When the strap I5 is inserted in recesses It in the members 5 and [2, Fig. 5, the member I2 is retained in its position. For the complete removal of the rail from the cross piece 5 there is provided a recess 63 through which the head of the pin Ill may be moved out. I v

The hip harness I may by means of a clamp H be connected with a waist strap l8. The free ends of the straps l4, [5, which ends are provided with hooks I9, may either be connected with the waist strap l8 as in Fig. 3, or the hooks I9 may be inserted in loops 20 connected with the hipharness. Straps 22, 23 are insertable in recesses 2| made in the rails 3, 4, whereby the packing may be fastened on the rails.

As the above described supporting frame is adapted to be taken to pieces, it may also be used for other articles than for rucksacks. Thus, when the supporting frame has been taken to pieces, the rails 3, 4 may be inserted in sleeves 25 sewed to a tent portion 24, and after the straps 22, 23 have been inserted through transverse recesses in the sleeves and through the recesses 2| in the rails respectively the tent portion may be folded about articles placed on the said portion, and the straps 22, 23 are strapped together about the packing thus obtained, as will be seen from Fig. 3. A sleeping-bag 26 provided with sleeves 25 may be connected with the supporting frame in an analogous manner, Fig. 6. In addition to not limiting the mobility of the carrier the supporting frame in question allows of a comfortable and safe transport. The construction according to the invention also creates increased possibilities of use for the supporting frameas, in the way described above, it may be combined with such articles as tent portions, sleeping-bags and the like.

Several embodiments are, of course, possible within the frame of the invention. Thus, the elements of the frame may be connected in other ways than those described above, and the members disclosed in the drawings and serving for holding together the elements may be replaced by other suitable members without going beyond the idea of the invention.

Having now described my invention, what I claim as new and desire to secure by Letters Patent is:

A supporting frame for a rucksack or the like having sleeves fastened thereto. comprising a hip harness, two substantially vertically extending rails adapted to be inserted into said sleeves, said rails having their lower ends flexibly connected with said hip harness, a cross piece connecting said rails at points spaced from said lower ends, said cross piece being provided with an elongated recess at substantially right angles to said rails and having a number of smaller recesses formed in one of the longer edges of said recess, a pin on one of said rails. said pin being insertable in any selected one of said smaller recesses. a member insertable in said elongated recess to fill the major portion thereof and to lock said pin in said selected recess, shoulder straps each having one end thereof connected to said cross piece, and means at the other end of each of said shoulder straps to engage said hip harness.
